Hi,my 2016 max plt. is on 2nd complete fill up,milage is around 925 now,and trips say my average is 27.9 to 28.4 that is mostly 25-50 mph city driving,i go intown 4-5 times a week and have 15 lights to stop at each way,and I run it in sport on reg. 87 octane up to this last tank,which I filled today with premium,so now I am hoping the milage has some increase,maybe 1-2 mpg,and I love sport,so when I drive it,thats where it will be.
